Project mention: The Elements of Differentiable Programming | news.ycombinator.com | 2024-03-22

I can't reply to the guy saying julia is the only one. But there are others.
Ceres uses dual numbers
https://github.com/ceres-solver/ceres-solver/blob/master/inc...
This library from google is used everywhere in robotics, so it's hardly some backwater little side project.
So does c++ autodiff

pixel-perfect-sfm

4 1,239 4.2 C++

Pixel-Perfect Structure-from-Motion with Featuremetric Refinement (ICCV 2021, Best Student Paper Award)

Project mention: On replacing Colmap | /r/GaussianSplatting | 2023-10-09

Are there alternatives available to the SfM pipeline? https://github.com/cvg/pixel-perfect-sfm for instance takes a deep NN to predict surfaces in the dense step ( not needed for GSplats), is a trained approach for spare reconstruction thinkable, are there other SfM methods that are significantly faster or find more features?
